STEP 1) Linking GPS tracking messages to your Iridium Phone number
The essential first step in setting up the GPS tracking is linking the tracking messages from your Iridium GO! to a phone number. The PredictWind server needs to identify your GPS tracking message. To complete this essential step, please click here for more information and let us know the following details, so we can create the customised tracking web page specific to your boat:
PredictWind username (email address)
Your Iridium phone number
The name of your boat
STEP 2) Activate the GPS Tracking on the Iridium GO! unit
The Iridium GO! needs to have the GPS tracking activated and setup. This can be done with the PredictWind Offshore App on a PC/Mac/iOS or Android device. You only need to do this step once.
PC/Mac Offshore App
Open the Offshore App on your PC/Mac and make sure you are connected to your Iridium Wi-Fi.
On a Windows computer, go to the top left corner of the screen > click on File > then click on Preferences.
On a Mac computer, click on 'PredictWind Offshore' in the top left corner of the screen > then click on Preferences.
Click on 'Iridium GO!'
Enter 'guest' as your username and password (this should not be changed).
Click 'Verify Settings.'
Turn your Tracking ON and your GPS ON.
Click on 'Apply Changes.'
Once these settings are saved, GPS tracking messages will be sent automatically every hour even if the PredictWind Offshore App is shut down. You will need to keep the Iridium GO! turned on for the GPS tracking messages to be transmitted. The tracking messages are sent via SMS, so there are no additional charges on the GO! unlimited, or GO! Plus airtime plans.
Alternatively, use the iOS/ Android Offshore APP
Open the Offshore App on your iOS/ Android device and make sure you are connected to your Iridium wifi.
Select Preferences from the main menu.
Tap on 'Iridium GO!'
Enter 'guest' as your username and password (this should not be changed and will be in there by default).
Click 'Verify Settings.'
Turn your Tracking ON and your GPS ON.
Click on 'Apply Changes'
Once these settings are saved, GPS tracking messages will be sent automatically every hour even if the PredictWind Offshore App is shut down. You will need to keep the Iridium GO! turned on for the GPS tracking messages to be transmitted. The tracking messages are sent via SMS, so there are no additional charges on the GO! Unlimited, or GO! Plus airtime plans.

Additional Information
NOTE: It is important to do the first download of your GPS tracks and blogs into the Offshore App on a high speed connection.
Please see an example of the tracking at
You can insert your customised tracking link into your website or blog. Alternatively, you can just email the website link to friends and family.
The GPS tracking is only available if you have bought your Iridium GO! SIM card from PredictWind, and have purchased the PredictWind Standard package. If you have not purchased the Iridium GO! SIM card from PredictWind you will need the Professional package.
If using GPS tracking on Iridium GO! Basic Plan, the cost for each SMS message is US$0.50. For GPS tracking, we suggest the GO! Plus Airtime/GO! Unlimited Plans, as these plans offer unlimited SMS messages for free.
Please note, your initial GPS position can take up to an hour to show on the map after first turning on the Iridium GO Tracking.
The “Track” button Iridium GO! App and the "Quick GPS Position" feature are not supported. These features are not necessary when you have the PredictWind automatic hourly GPS position reporting.
The preset default numbers in Iridium GO settings should not be changed.
